How to make this curve in Pro/Engineer?
to be honest i tried and wasn't able to make it (my knowledge is still rudimentary),
my line of approach was making single helix datum curve using equation with two turns,then copying into different planes,connecting ends of helix to each other. then variable section sweep.
At least you tried.. :)
tôi đã cố gắng tạo ra nó, và chưa thật sự hoàn hảo
I tried to create it, and not really perfect.
hy vọng bạn có thể làm tốt hơn tôi, và cho tôi một hướng dẫn cụ thể.
hope you can do better than me, and give me a specific instructions.
